Parks 2050: Growing food, curbing floods, cleaning air

Have you ever noticed a certain similarity in public parks and back gardens in the cities of the West? A ubiquitous woodland mix of lawn grasses and trees has found its way throughout Europe and the United States, and it’s now spread to other cities around the world. As ecologist Peter Groffman has noted, it's increasingly difficult to tell one suburb apart from another, even when they're located in vastly different climates such as Phoenix, Arizona, or Boston in the much chillier north-east of the US. And why do parks in New Zealand often feature the same species of trees that grow on the other side of the world in the UK?
